Tropical Aqua-Alkal pH Plus

Tropical Aqua-Alkal pH Plus is a freshwater pH-raising treatment designed for aquarists keeping species that thrive in alkaline conditions. Whether you're maintaining a Malawi cichlid biotope, a Lake Tanganyika Tropheus setup, or a Central American cichlid system, stable, elevated pH is a non-negotiable part of the environment — and this treatment is built specifically for that job.

Why pH Stability Matters

Many popular cichlid species have evolved in naturally alkaline lakes where pH remains consistently high. In a closed aquarium system, natural biological processes can cause pH to drift downward over time. Tropical Aqua-Alkal pH Plus counteracts this drift, helping maintain the alkaline conditions these fish depend on for good health, strong colouration, and successful spawning.

How to Use It Safely

When dosing directly into an established aquarium, pH changes should never exceed 0.2 pH per day — sudden shifts cause stress regardless of the direction. For the most controlled approach, prepare treated water in a separate vessel and introduce it to the tank gradually. Always monitor pH throughout the process using a reliable aquarium test kit.

Recommended Test Kits

To dose accurately and track water chemistry, use alongside a suitable pH or multi-parameter test kit. Compatible test options include Test 6-in-1, Test pH 4.5–9.5, Test pH 6.0–7.8, and Test GH/KH — all available at Viperia.

Available Sizes

Tropical Aqua-Alkal pH Plus is available in two sizes to suit different tank volumes and dosing frequencies. Choose the size that fits your setup and maintenance routine from the options on this page.

A straightforward, targeted treatment for keepers who understand that water chemistry is as important as any other aspect of aquarium husbandry. Used correctly alongside regular testing, it takes the guesswork out of maintaining alkaline conditions long-term.
